The historical significance of the development of optical image stabilizers by Panasonic Corporation is briefed in what follows.

1. Historical Background of Developing the Optical Image Stabilizer.

For more than a decade, Image Stabilization (IS) technology has been considered essential to delivering improved image-quality in professional cameras. More recently, as a result of advancing technology, IS has become increasingly popular to handheld device makers who want to propose high-end features for their products. Hence, manufacturers like Panasonic have worked hard on its technologies and methods for image stabilization to significantly improve camera shutter speed and to offer precise suppression of camera vibration [2].

Today, from the technological point of view, Digital Image Stabilization (DIS), Electronics Image Stabilization (EIS), and Optical Image Stabilization (OIS) are the best understood and the easiest to integrate in digital still cameras and smartphones, although they can produce different image quality results: In fact, DIS and EIS require large memory and computational resources on the hosting devices, while OIS acts directly on the lens position itself and minimizes memory and computation demands on from the host. As an electro-mechanical method, lens stabilization (optical unit) is the most effective method for removing blurring effects from involuntary hand motion or shaking of the camera [2].

Thus, at the time when there occurred the strong demand for OIS to avoid camera blur, Panasonic soon made desperate efforts to develop OIS technology.

2. Panasonic’s Development of OIS

Every Panasonic camera has an OIS. This OIS compensates for hand shake and camera movement in all four directions, up, down, left, and right. A gyro-sensor detects tiny movements of the camera and moves the OIS lens in the opposite direction to steer the image onto the image sensor. This reduces blurred images that normally occur as a result of camera movement. In addition, the OIS is particularly effective when taking pictures where you are zoomed in, at a distance from the subject. Using a high magnification (zoom) exaggerates the effect of camera movement, causing increased image blurring. OIS compensates for this movement, producing a clear picture [3]. 

Panasonic was the first to introduce two OIS modes into digital cameras. Mode 1 continually tracks the camera movement, even when framing up the shot (before taking the picture), while Mode 2 only compensates for camera movement when the shutter button is pressed (as the image is captured):

In more detail, Mode 1 continually compensates for camera movement, even when framing up the subject. This is useful if you have shaky hands and when using high zoom levels. It is easier to see the subject in the viewfinder or on the LCD screen. Model 1 has the disadvantage that the OIS lens may not be able to move from one extreme direction to the other in time to compensate as the photograph is taken. In this respect it can be less effective than Mode 2. On the other hand, Mode 2 keeps the OIS lens in the center when framing up the subject. When the shutter button is pressed, the OIS calculates the movement and compensates. Because the OIS lens is in the central position, it has less distance to move to any of the extremes of the picture and will be better able to compensate for any camera movement. This is the most effective mode for image stabilization, but the OIS is not available to assist with framing up the subject [3].

What obstacles (technical, political, geographic) needed to be overcome?

The Digital Still Camera (DSC) market has moved towards smaller sizes, lower weight, and higher resolutions, much as mobile camera modules have followed the same trend after their introduction in smartphones and handsets. A big drawback to this development has been the impact of blurring, caused by involuntary motions, on image quality. In fact, lighter cameras produce greater blurring. In addition, the introduction of larger LCD displays has encouraged users to take pictures with outstretched arms, further increasing blurring [2].

The introduction of Image Stabilization (IS) in several mobile platforms has been a significant added value for photography lovers, especially for younger users, who replaced their traditional and bulky cameras with brand-new smartphones, or had cameras available to record memories, simply because those cameras were embedded in the mobile platform they were already carrying. IS in smartphones enables pictures and video with quality comparable to DSCs in so many operating conditions. As a consequence, the request for IS is increasing both in compact DSCs and smartphones [2].

What features set this work apart from similar achievements?

A number of distinctive features associated with OIS are outlined briefly in what follows [2]:

1. Picture blurring caused by hand jitter, a biological phenomenon occurring at a frequency below 20Hz, is even more evident in higher resolution cameras. In fact, in smaller resolution cameras the blurring may not exceed one pixel, which is negligible; but in higher resolution ones it may impact many pixels, thus degrading image quality significantly.

2. OIS technology is an effective solution for minimizing the effects of involuntary camera shake or vibration. It senses the vibration on the hosting system and compensates for these camera movements to reduce hand-jitter effects. Thus, OIS captures sharp pictures at shutter speed several times slower than otherwise possible.

3. The increase of the shutter opening time permits more brilliant and clear pictures in indoor or low-light conditions. The time during which the shutter remains open, regulates the amount of light captured by the image sensor. The longer the exposure time, the greater the potential for hand shaking to cause blurring.

4. In the case of smartphones cameras, because of their small lens apertures and the material used to make unbreakable lenses, the amount of light that can enter and strike the image sensor is significantly less than that of a DSC. This requires a higher exposure time, with the obvious drawback of increasing the effect due to shaking hands.

5. Besides the optical requirements, two main challenges in the development of OIS in smartphones are size and cost. The additional hardware required to implement OIS increases the total cost of camera as well as camera’s size. This runs counter to the constant market demand for smaller and thinner devices.
